A portfolio of simple, practical models is presented for a) the resistance of a RC member in flexure or shear under cyclic loading; b) its deformation at flexural yielding and its secant-to-yield-point stiffness; and c) the member ultimate deformation in flexure or shear under cyclic loading. They are based on a databank of several thousand tests of RC members - the largest in the world. They cover beams, rectangular columns or walls, members with circular, T-, H-, U- or hollow rectangular section, with or without detailing for earthquake resistance, with bars ribbed or smooth, continuous or lap-spliced in the plastic hinge. Most of the models, or earlier versions based on a smaller data-bank, were adopted in Eurocode 8-Part 3 and/or fib MC2010, for performance- and displacement-based seismic design, assessment or retrofitting. So, the paper serves as a background document for the models adopted in these codes, improving and extending them, or presenting new ones.
